    I have ccd installation here , which is based on
    ccd v.1.7 of 01-96. Now I want to upgrade the machine
    to the 2.2-960612-SNAP , whih carries ccd as pseudo-device.
    The ccd version in this SNAP is 1.13.

    Is it possible to use old ccd drive with this release ?
    Will system recognize it or I have to "newfs" ccd drives ?
    The machine serves Usenet news and I can't afford to loose
    whole news partition :(

	I vaguely remember something about new version of CCD being
	somehow incompatible with the old ones.

	The same time I heard that AHA2940 code is now much more
	robust and VM system was also cleaned out quite bit.

	AHA2940 though is  the main concern - resets and timeouts
	on SCSI bus are really annoying.

    Is it possible to install ccd v 1.7 in 2.2-960612-SNAP ?
    ( w/o activating pseudo-driver one)?
